Abstract:

Abstract:The water requirement ratio is an important indicator for the coal ash quality evaluation of coalfired power unit. In order to improve the coal ash quality and its economic benefits of power plant, this paper analyzed the influence factors of coal ash water requirement ratio based on the waterreducing effect mechanism of coal ash, including the fineness, loss on ignition and particle shape, etc.,and introduced the current technologies and methods of reducing coal ash water requirement ratio in China and abroad.
